|
|
<div class="p">After you have configured the primary <a href="rzakhconfigpase.htm#rzakhconfigpase">Kerberos
|
|
server in i5/OS™ PASE</a>,
|
|
you can optionally configure a secondary Kerberos server to use as a backup
|
|
server in case your primary Kerberos server goes down or is too busy to handle
|
|
requests.<p>For example, you currently use iSeries™ A as your Kerberos server. Now
|
|
you want to configure iSeries B to be your secondary (backup) Kerberos
|
|
server.</p>
|
|
<div class="note"><span class="notetitle">Note:</span> A Kerberos server is also known as a key distribution center
